A core bit is a specialized accessory designed for use with a core drill.
Core bits are used to drill into hard materials, including applications in oil well drilling and construction. They are particularly effective for boring through concrete and bricks, and creating samples for testing the compressive strength of concrete or mortar. Common uses also extend to installing guardrails, fences, and other structures.
There are various types of core bits, such as roller cone and diamond core bits. Diamond core bits are especially notable for their extreme hardness, making them suitable for cutting through tough materials. Their durability also allows for long-term, extensive use.
